Follow-Up on Khayelitsha Streetlights

In February, GroundUp published a report on the issue of street lights in Khayelitsha, in particular on Lansdowne Road and Mew Way. Activist organizations — the Social Justice Coalition (SJC), Treatment Action Campaign (TAC) and Equal Education (EE) — held a march on 4 February in Khayelitsha.We have a great selection of blown glass backyard solar landscape lights and solar garden light.

City of Cape Town Mayor Patricia De Lille, who attended the march, received a memorandum that the City should ensure that street lights were functioning in Khayelitsha. It also demanded that the City implement the installation of street lights where they were not available and fix damaged and vandalized lights within Lansdowne Road and Khayelitsha.

GroundUp ran a follow-up story in April, and it seems there has been some improvement.

Councillor Danile Khatshwa of Ward 96 (Makhaza in Khayelitsha) said street lights in his ward from Lindela Road to Baden Powell Drive have been fixed and are working.

“Since I submitted complaints from residents within my ward, the street lights have been fixed and are functioning. You would only find that about one or two street lights are not working, but I can say that there’s been an improvement,” he said.

Zodwa Sinkempele (20), a Community Librarian at Equal Education said that she has some mixed feelings when it comes to the issue of street lights. “Since the march, I have seen some improvement in the functioning of the [street] lights. But I don’t know whether the City only fixed the lights because we were pressuring them, or they only fixed the lights to get us out of their way then discontinued with the work they were supposed to do.”

Khatshwa admitted there are however some parts of Khayelitsha that still remain in the dark.

“Despite the improvements on street lights in Makhaza, major sections in Khayelitsha still remain without functioning street lights,How does a solar charger work and where would you use a solar charger? particularly along Lansdowne Road .. Even some of the newly implemented streetlights are not of the best quality.”

Councillor Danile felt that the newly installed lights were not as bright as the previously installed lights,A solar lantern uses this sunlight that is abundantly available to charge its batteries through a Solar Panel and gives light in nighttime. and felt that much brighter streetlights should have been installed. GroundUp went out at night to see whether this statement was true. The streetlights at Makhaza are very bright, and about 15 floodlights are providing light for the Site B, Town Two and Makhaza areas.

In addition to the three small bedrooms, the one-story house has two discreet sleeping lofts.

“We wanted small rooms,” says Mr. Christiansen, which he says encourages the family to get together in the large central living and dining area. The master bedroom has a wall that opens entirely onto a private deck overlooking a tree-lined yard.

They hoped to finish by Christmas 2011, but delays on foundation and basement work meant a half-year postponement. They finally moved in July 2012, spending more than $500,00 on the project.

A basement is unusual for a summer house in the area, says Mr. Christiansen, but it was necessary to conceal the complicated technology involved in making the house energy efficient. Outfitted with a heat pump, solar panels and photovoltaic cells, the house can generate all of its heating, and can contribute electricity to the grid when the family is away.

Triple-glazed windows and near-total insulation mean that controlled ventilation is essential, and the house is programmed to ventilate itself four times a day. Heating can be controlled by a smartphone app,Shop funtional and elegant solar lights, outdoor solar lighting, solar garden lights, path lights and decorative solar lights. which allows the house to be just the right temperature when the family arrives for winter weekends.

In addition to the main house, the property has a new free-standing sauna, lined with ash wood and equipped with a large picture window. The wood-burning sauna oven is imported from Finland. Mr. Christiansen designed the sauna himself. “It is beautiful sitting here in 175-degree heat,” he says, of his winter sauna sessions, which end with a roll in the snow.

Saunas aren’t rare in Denmark, but “most Danes who build a sauna end up using them for storage,” says Mr. Christiansen. The couple, looking ahead to the property’s resale value, built the sauna to be easily converted into a guesthouse.

It sounds like magic, far-out fiction, a California dream. Yet earnest scientists are hard at work on a new alchemy: brewing fuel for cars — synthetic gasoline — from little more than water and sunshine.

Mimicking the way plants turn sunlight and carbon dioxide in the air into energy and oxygen, the Joint Center for Artificial Photosynthesis at the California Institute of Technology is in a race to trump nature and slow global warming. Nate Lewis, a Caltech professor and solar energy research star, has a plan to remake fuel as we know it.

“If we couldn’t get to that, we wouldn’t be doing it,” Lewis said in an interview last month.

The effort is backed with $122 million of U.S. Energy Department funds and combines the talents of 120 scientists at Caltech; Stanford University; the University of California’s Berkeley,How does a solar charger work and where would you use a solar charger?Shop funtional and elegant solar lights, outdoor solar lighting, solar garden lights, path lights and decorative solar lights. Irvine and San Diego campuses; and Lawrence Berkeley National Laboratory.

Along with electric powertrains, vehicles that drive themselves and cars rented by the hour, it’s another disruption of the global auto industry that dates back to the 19th century.

Just a few years ago, all-electric cars seemed fantastic, too. Now Tesla Motors Inc. (TSLA), which makes only battery-powered vehicles, has a higher market value than some old-line automakers, such as Suzuki Motor Corp. (7269) and Fiat SpA. (F)
Two Leaps

To revolutionize transportation fuel, Lewis has a two-step plan. Really, it’s two leaps.We carry a extensive line of Parking Lot Lighting inventory.

First, the coalition aims to develop a system to make large amounts of hydrogen fuel using cheap solar-panel-like devices. Liquid or gaseous hydrogen, which can power super-clean fuel-cell cars, is needed for chemical plants and refineries.

Then comes the second leap: Applying that same research to a system that can blend the hydrogen fuel with carbon dioxide from the air, much as a plant does, to make liquid fuels that can power cars, heavy trucks, boats or aircraft. JCAP aims to get to that point by the mid-2020s, Lewis said.

Synthetic, carbon-free gasoline won’t come easy, quick or cheap.

Research labs worldwide are racing to find renewable alternatives to petroleum. Some are private endeavors; others are government-funded. While some seek to make fuel from algae, corn or other crops, Lewis argues that such solutions require too much water or land that will be needed for food production.
Innovation Race

Research projects like JCAP have the luxury of not having to satisfy investors’ short-term demands, said Pavel Molchanov, a Houston-based analyst for Raymond James & Associates Inc.

“Companies that rely on private capital, even venture capital, in most cases aim to be commercial within the next three years,” said Molchanov, who follows biofuel companies. “If we think about what private developers of biofuels are focusing on now, none of them have a commercialization road map that goes out to 2025.”

Startups such as KiOR Inc., Solazyme Inc., Ceres Inc., Gevo Inc. and Amyris Inc. have a lead over JCAP because they’re already commercializing biofuel alternatives to petroleum and grain-based ethanol.

What JCAP has going for it is the Energy Department, which deemed it an Energy Innovation Hub, one of three Manhattan Project-like efforts. Others are to improve nuclear power plants and make buildings more energy-efficient. With the government funding, Lewis can be methodical in search of a breakthrough.
Wright Brothers

“The first five years of JCAP, our goal is to show that this can be done; to make the pieces, components, to build an artificial photosynthetic system,” he said. That prototype “isn’t going to be commercializable,We have a great selection of blown glass backyard solar landscape lights and solar garden light. in the same way the Wright Brothers’ plane wasn’t a 747. We first have to show people there’s a there there.”

About five years after that, with “faster, better, cheaper” fuel-making technology, JCAP may be able to license its system to oil and energy companies, Lewis said.

The program is talking with potential industrial partners to help expand its analysis of promising “earth-abundant” materials needed for its solar-fuel distillery. Lewis declined to identify specific companies. JCAP’s technicians daily are testing hundreds of alloys made from metallic salts, seeking the optimal recipe of low-cost, light-absorbing materials and catalysts needed for hydrogen generation.

Urgency to increase low-carbon energy sources has intensified as extreme weather adds to concerns that heat-trapping gases in the atmosphere are making the Earth a less hospitable planet.

President Barack Obama, whose administration funded JCAP, signaled in June that U.S. action to curb carbon emissions will intensify with new steps to pare such pollution from power plants,A solar lantern uses this sunlight that is abundantly available to charge its batteries through a Solar Panel and gives light in nighttime. the biggest source of carbon dioxide emissions, according to the U.S. Environmental Protection Agency.
Transportation Fuels

Second is the use of petroleum-based fuel in transportation. Engines in autos, trucks, aircraft and ships produced 28 percent of the 6.7 million metric tons emitted by the U.S. in 2011, according to the EPA, trailing only electricity generation’s 33 percent. Obama also laid out a plan in 2011 to double vehicle fuel efficiency by 2025 to cut carbon pollution.

Carmakers are boosting vehicle efficiency with small, high-output engines; propulsion delivered by batteries; and even hydrogen fuel cells.
